Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of the coupling of the sprinkler head according to an embodiment of the present invention.

Referring to FIG. 1, the sprinkler head includes a frame 100, a body 200, a deflector 300, a support part 400, and a thermal part 500.

Frame 100 is coupled to the piping of the building ceiling.

The body is coupled to the frame 100 and is normally coupled to the support 400 to separate the support 400 during melting of the fuse 510.

The deflector 300 is located inside the body 200 to normally close the waterproof port 110, and includes a water injection port 330 protruding to the outside in the event of a fire to discharge the extinguishing water discharged from the waterproof port (110). .

The support part 400 supports the deflector 300 and has a plurality of support surfaces for dispersing the restoring force of the C-shaped spring 410, and prevents deformation of the fuse 510 of the thermal part 500.

The heat sensing part 500 includes a heat collecting plate 530 disposed under the support part 400, and houses the fuse 510 and senses an external temperature.

The frame 100 is coupled to a pipe (not shown) provided on the building ceiling and coupled to the body 200. The deflector 300 is positioned inside the body 200, and the support part 400 and the thermal part 500 are sequentially stacked.

The body 200 is coupled to the support 400 to fix the deflector 300 located therein to prevent the waterproof port 110 of the frame 100 to prevent the discharge of the usual extinguishing water.

The deflector 300 prevents the discharge of the extinguishing water by blocking the waterproof port 110 of the frame 100 at all times and effectively discharges the extinguishing water ejected from the waterproof port 110 in case of fire. Looking at an embodiment of the coupling relationship of the deflector 300 in more detail, the packing 310 is attached to the packing groove 320 of the deflector 300 is in close contact with the bottom of the waterproof port 110. When the fuse 510 is melted, the deflector 300 fixed by the support part 400 is fixed to the deflector catching groove 340 of the deflector 300 by being fixed to the body groove 210. The injection port 330 protrudes to the outside to extinguish the fire extinguishing water discharged from the waterproof port 110 to the water injection port 330 to extinguish the fire.

The support unit 400 is located below the deflector 300 to support the deflector 300 and is located above the heat sensitive part 500. When the fuse 510 of the heat sensitive part 500 is melted in a fire, a waterproof hole ( The deflector 300 blocking the 110 is quickly caught in the body groove 210.

Looking at one embodiment of the coupling relationship of the support unit 400 in more detail, the lower cap located in the lower portion of the deflector 300 to support the deflector 300 and the lower portion located below the upper cap 420 Support 430 is coupled by the restoring force of the C-shaped spring 410 located between the spring engaging groove 432c of the lower support second bending portion 432 and the spring fixing groove 220 of the body 200, the spring It is coupled to the body 200 by the C-shaped spring 410 fixed to the fixing groove 220, the spring engaging groove 432c, the upper cap third bent portion 423 of the upper cap 420. The C-shaped spring 410 represents a form in which a part of the closed curve is opened, and the shape of the closed curve may be variously modified.

In addition, the horizontal cross section of the present invention is not limited to a circle, but may be modified into various polygons.

The lower support second bent portion 432 is provided with an inclined surface 432b to quickly and easily restore the spring, so that when the fuse 510 is melted, the C-shaped spring 410 is quickly and easily restored when the fire occurs. Fire can be put out quickly.

In addition, in order to prevent the malfunction of the sprinkler head caused by deformation of the fuse if the pressure applied to the fuse 510 of the C-shaped spring 410 is prolonged for a long time, the upper portion for supporting and dispersing the pressure applied to the fuse 510 The upper cap first bending portion 421 of the cap 420, the upper cap second bending portion 422 and the lower support first bending portion 431 of the lower support 430, the lower support second bending portion 432 It is provided.

In order to effectively block the restoring force of the C-shaped spring 410, the lower support second bent portion 432 is provided with a spring engaging groove 432c to effectively block the pressure, the fifth support is located at the end of the inclined surface (432b) The surface 432a contacts the third supporting surface 422a of the upper cap 420 to cancel the pressure.

Similarly, the fourth support surface 431a of the lower support first bent portion 431 and the second support surface 421b of the upper cap first bent portion 421 and the first support of the upper cap first bent portion 421 The surface 421a and the outer surface of the bolt 550 abut each other to cancel the pressure.

As a result of the interaction of the various support surfaces, the restoring force of the C-shaped spring hardly affects the fuse 510, thereby preventing malfunction of the sprinkler head due to deformation of the fuse 510. The fuse 510 may be variously modified into a material that is melted or extinguished by heat during fire such as a low fusion alloy such as lead, plastic, rubber, and wood.

The thermal part 500 is to quickly detect the heat during the fire, Looking at the specific embodiment in more detail, the fuse 510 is inserted into the heat collecting plate groove 540 provided in the heat collecting plate 530 fuse 510 And protect the fuse 510 by providing an insulating washer 520 on the upper portion of the fuse 510. The insulation washer 520 may be made of a material having a slow heat transfer to concentrate the fuse 510 while preventing heat transmitted from the heat collecting plate 530 to the surroundings, thereby improving a heat sensing function.

3 is an operation cross-sectional view (in case of fire) of the sprinkler head according to an embodiment of the present invention. As shown in FIG. 3, when the fuse 510 is melted at the time of fire, the upper cap 420 and the lower support 430 of the support part 400 provided at an upper portion of the fuse 510 are C-shaped springs. The coupling is released by the restoring force of 410. At the same time, the deflector 300 which is separated from the body 200 and blocks the waterproof port 110 of the frame 100 by the support part 400 protrudes to the outside, and the digestive water is ejected from the water injection port 330 of the deflector 300. Very fast fire fighting is possible.

That is, as soon as melting of the fuse 510 is started, the structure of the upper portion is released from the digestion water as quickly as possible. As shown in FIG. 3, when the fuse 510 is melted, the support part 400 and the thermal part 500 of the upper structure may be discharged to the outside.

Therefore, as described above, the sprinkler head of the present invention prevents the deformation of the fuse 510 so that the fuse 510 does not deteriorate even in the event of a fire after a long time, and performs a rapid heat detection function to accurately discharge the extinguishing water. To achieve.

Although the present invention has been shown and described with reference to the preferred embodiments as described above, it is not limited to the above embodiments and those skilled in the art without departing from the spirit of the present invention. Various changes and modifications will be possible.

The present invention relates to a sprinkler head that is coupled to the pipe of the building ceiling, by dispersing the pressure of the fuse by the support surfaces provided in the support to prevent deformation of the fuse even after a long period of time, when the fire occurs C Due to the restoring force of the mold spring, it can be applied to buildings over a certain size by quickly and precisely extinguishing the fire, thus preventing the malfunctions in a normal way, so that it can safely and quickly extinguish the fire.
